What are the steps of injection molding? Safety is productivity. The injection molding process is cumbersome and interlocking, and one cannot be dispensed with. A flaw in any of these links may lead to poor quality of injection molding and affect the molding effect of plastic parts. Shanghai Mulan Injection Molding Processing Factory needs to strictly follow the molding steps when performing injection molding processing. Then, injection molding
What are the steps in molding?
Shanghai Mulan Injection Molding Factory focuses on the customized business of small household appliances, household beauty instruments, and maternal and child products. It has accumulated experience in product development, mass production management, and quality management. It provides customers with appearance design, sample production, circuit development, Structural design, mold design, mold processing, overmolding, two-color mold, injection molding processing, two-color injection molding, overmolding injection molding, finished product assembly, reliability test, dimension measurement and other one-stop manufacturing solutions. Strictly implement the following steps in injection molding:
1. Raw material heating and premolding: Before injection molding, the raw material needs to be heated and dried to discharge excess water, and then conveyed by the screw. Through the interaction of heater, screw and barrel, the raw material is melted;
2. Mold clamping and locking: the movable mold part of the mold is clamped and locked with the movable mold part of the mold on the movable platen to ensure that sufficient clamping force can be provided during molding;
3. The injection device moves forward: after the mold is clamped and locked, the injection seat moves forward, and the nozzle of the injection molding processing machine fits the main sprue of the mold completely;
4. Injection holding pressure: the injection hydraulic cylinder enters the high-pressure oil, pushes the barrel, and injects the melt in the barrel into the mold cavity. In order to ensure the tightness and dimensional accuracy of plastic parts, it is necessary to maintain a certain pressure on the melt in the mold cavity;
5. Pressure relief: When the mold gate melt cools and condenses, it can relieve pressure;
6. The injection device retreats: after the pressure relief is completed, the screw can retreat to complete the next feeding and pre-molding;
7. Mold opening and ejection of plastic parts: After the plastic parts in the mold cavity are cooled and shaped, the mold locking mechanism opens the mold and pushes out the plastic parts.
The above is a brief introduction of the steps of injection molding by Shanghai Mulan Injection Molding Factory. If you are looking for injection molding processing solutions, welcome to consult our 20-year injection molding experience master online, or pick up the phone to contact us, we will wholeheartedly provide you with reasonable technical solutions.
